Abstract
The invention adopts the technical scheme that an optical fiber combiner comprises a plurality of optical fibers and a jacket, wherein one segment at one end of the optical fibers is peeled to expose the claddings of the optical fibers, the peeled segments of the optical fibers are hooped by the jacket, and the optical fibers are mutually fixed through a fixed object at a place where a protecting layer is not peeled at the other ends of the optical fibers. In the invention, the peeled segments of the optical fibers are hooped by the jacket, and the optical fibers are mutually fixed by selecting a proper position at the place where the protecting layer is not peeled to finish the optical fiber combiner capable of bearing high-power laser. Because each cladding is not damaged, the optical fiber combiner can bear the high-power laser, and the manufacturing method is simple.
Description
[technical field]
The present invention relates to the optical-fiber bundling device that a kind of high power laser uses.
[technical background]
The optical-fiber bundling device of current trend is to be fused to the bundling device that an optical fiber mode is made by multifiber, and we abbreviate the existing fiber bundling device as.Owing to the process of drawing the awl welding is arranged, has about 5% to 10% luminous energy loss here.Because covering and fibre core are fused together, this can cause welding point refractive index to have uneven place, causes scattering and heating easily, and is particularly unfavorable for the transmission of high power laser light.
Moreover the existing fiber bundling device needs the high temperature welding, and manufacturing process is comparatively complicated, needs experience higher.
[summary of the invention]
The problem that institute of the present invention desire solves just provides the optical-fiber bundling device that a kind of method for making is simple, bear high power laser light.
The technical solution adopted in the present invention is: a kind of optical-fiber bundling device; comprise: multifiber and sheath; one end of this multifiber is peeled one section off; the covering that exposes this multifiber; described sheath is waled a section that this multifiber has stripped, and the place that the other end of described multifiber is not peeled protective seam off fixes with each other this multifiber by a fixture.
Wherein, described sheath is a pottery or for glass or for sapphire or for ruby or for garnet or for quartzy.
Wherein, described sheath is made by abrasive substance.
Wherein, be provided with the endoporus of fixed fiber in the described sheath.
Wherein, described endoporus be shaped as circle or for triangle or for square or for sexangle or for irregularly shaped.
Wherein, an end of described sheath pours into melted material, and the slit between the multifiber of waling is filled up.
Wherein, described fixture is a viscose glue.
Wherein, an end of described sheath pours into melten glass or the more quartzy low-melting melted material of other fusing points.
Wherein, described sheath is used mask method filling up on end face glass, ground, and only at the end face plating laser of the glass film that is all-trans, and the end face separately of multifiber is kept intact or plated the laser anti-reflection film.
The present invention selects a suitable position that this multifiber is fixed with each other by sheath being waled one section that multifiber has stripped in the place of not peeling protective seam off, finish an optical-fiber bundling device that can bear high power laser light with this.This optical-fiber bundling device can bear high power laser light because covering does not separately damage, and method for making is simple.
[description of drawings]
Fig. 1 is the structural representation of optical-fiber bundling device of the present invention;
Fig. 2 is the synoptic diagram of the face off of optical-fiber bundling device shown in Figure 1.
[embodiment]
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
The present invention relates to a kind of optical-fiber bundling device, as Fig. 1, comprise multifiber 10 and sheath 30, an end of this multifiber is peeled one section off, allows the fibre cladding of this multifiber 10 expose; But described sheath 30 is made (as Fig. 2) by abrasive substance, as pottery or be glass or for sapphire or for ruby or garnet or be quartz.
This sheath 30 is waled a section that described multifiber 10 has stripped, and selects a suitable position in the place of not peeling protective seam off, and this multifiber 10 is fixed by a fixture 20, and this fixture 20 is a viscose glue.
By sheath 30 being waled an end of multifiber 10, then finish an optical-fiber bundling device that can bear high power laser light.
One end of described sheath 30 pours into melten glass or the more quartzy low-melting melted material of other fusing points, and the slit between the multifiber of waling 10 is filled up, and treats to grind this end face again behind glass or the other materials cooling curing.
Described sheath 30 also can fill up on end face glass, ground with mask method only at the end face plating laser of the glass film that is all-trans, and keeps intact or plate the laser anti-reflection film at the end face separately of multifiber 10.
Be provided with the endoporus of fixed fiber in the described sheath 30, this endoporus can be selected different shape according to the difference of number of fibers, as: circle, triangle, square, sexangle or irregularly shaped etc.
The bundling device that the present invention makes like this because covering does not separately damage, can bear high power laser light, and method for making is simple.
